IntroductionWhy study Iwilei and Kapalama?• Integrating complete streets and “green”
development and infrastructure strategies into future TOD can:– Improve sustainability and climate
resiliency– Improve access and safety for all: people
cycling, walking, driving, or on transit– Create, connect to, and catalyze healthier,
more livable places– Sites where chosen because the solutions
and strategies can be replicable in other areas of the city
Implementation Projects/Studies Underway
• Iwilei/Kapalama Infrastructure Master Plan
• Infrastructure Financing Strategies• Kapalama Canal Catalytic Project• Iwilei Drainage Study• Affordable Housing Strategy• EPA Greening America’s
Communities • EPA Brownfields Grant Program
